Manage OpenPGP keys

OpenPGP is a tool for secure online communication. CPanel uses GnuPG for its
public-key cryptography so that users may communicate securely. Each person
gets a pair of keys, called the public key and the private key. Each person's
public key is published while the private key is kept secret. Messages are encrypted
using the intended recipient's public key and can only be decrypted using their
private key.

General documentation and comprehensive user guides are available at the GNU Privacy Guard site.
